Bats are flying mammals in the order Chiroptera (pronounced /kaɪˈrɒptərə/). The forelimbs of bats are webbed and developed as wings‚ making them the only mammals naturally capable of true and sustained flight. By contrast‚ other mammals said to fly‚ such as flying squirrels‚ gliding possums and colugos‚ glide rather than fly‚ and can only glide for short distances. Bats do not flap their entire forelimbs‚ as birds do‚ but instead flap their spread out digits‚[2] which are very long and covered with

Introduction The pollination involves the transfer of pollen from male part of a plant‚ called stamen to the female part of the plant‚ known as carpel. This enables fertilization and sexual reproduction to occur. Pollen grains are contained within the pollen while the carpel contains the female gamete. In gymnosperms the pollen is directly applied to the ovule. The receptive part of the carpel is called a stigma in the flowers of angiosperms while the receptive part of the gymnosperm ovule

My journal entry began when I started learning about the eras of geologic time like the Paleozoic‚ Mesozoic‚ and Cenozoic eras. Although the various time periods were all very interesting‚ I found the Paleozoic era to be the most fascinating.’Paleo’ means ancient or way early times in Greek and therefore Paleozoic means ancient life. This era was divided into six major parts. These parts are named the Cambrian‚ Ordovician‚ Silurian‚ Devonian‚ Carboniferous‚ and Permian periods. The Ordovician period

of the skeleton. The small‚ plant-eating Thescelosaurus‚ nicknamed ‘Willo’ has been acquired by the North Carolina Museum of Natural Sciences. Thescelosaurus was an ornithischian‚ or "bird-hipped‚" dinosaur that lived in the latter stage of the Cretaceous period. This was approximately 1 million years before the end of the dinosaur era. Native to North America‚ its range extended from the northern United States up into Canada. Since using the 3-D software to reveal Willo ’s heart‚ scientists have

It is not easy to really get a "feel" for 4‚600 million years! One way to try to get a "feel" for how big it is‚ is to break the number down into smaller pieces that perhaps we can understand. Plants and animals have changed many times‚ from amoebas to dinosaurs to people. The
